android-menudrawer *DEPRECATED* A slide-out menu implementation, which allows users to navigate between views in your app.
CircleMenu CircleMenu is a simple, elegant menu with a circular layout.
CircleProgressMenu A simple circle menu with progress effect.It's used for some projects that need to be done step by step.The default color of the circles around is dark grey, The color of a certain circle will turn green when you are doing tasks involved in it and then blue when you complete them.Of course ,you can change these three status colors as you like at xml.Just copy my code if you need such a menu, which is quite easy to understand. Any suggestion, please send Thank you!

compile 'org.zakariya.flyoutmenus:flyoutmenu:0.5.3'
  • minSdkVersion: 14 Note: when running on SDK less than 18, hardware rendering is disabled. This means that button shadows are clipped. To work around this, add a bit of padding to the view.




FlyoutMenuView attributes (all have fm prefix) are:

// the size of the button
<attr name="fmButtonSize" format="dimension"/>

// the background color of the trigger button
<attr name="fmButtonBackgroundColor" format="color"/>

// the background color of the menu
<attr name="fmMenuBackgroundColor" format="color"/>

// the color drawn behind the selected menu item
<attr name="fmSelectedItemBackgroundColor" format="color"/>

// width of items in the menu
<attr name="fmItemWidth" format="dimension"/>

// height of items in the menu
<attr name="fmItemHeight" format="dimension"/>

// margin around items in the menu
<attr name="fmItemMargin" format="dimension"/>

// menu anchoring position (see below)
<attr name="fmMenuAnchor" format="string"/>

// margin around the menu - menu will be positioned this far away from the button, but 
// will also use this to respect screen edges
<attr name="fmMenuMargin" format="dimension"/>

// if provided, the trigger button will use this as a drawable
<attr name="fmButtonSrc" format="reference"/>

// elevation for the trigger button. if 0, no shadow is drawn
<attr name="fmButtonElevation" format="dimension"/>

// elevation for the menu. if 0, no shadow is drawn
<attr name="fmMenuElevation" format="dimension"/>

// if true, a shield (like for dialogs) is drawn behind the menu
<attr name="fmShieldVisible" format="boolean"/>

// color of shield drawn behind menu, if shieldVisible == true
<attr name="fmShieldColor" format="color"/>

// if true, menu operates in "tap to open", "tap to select and dismiss" mode
<attr name="fmDialogMode" format="boolean"/>

The fmMenuAnchor attribute takes the following values:

  • top : menu attached above the button
  • right | end : menu attached to right of button
  • bottom : menu attached beneath button
  • left | start : menu attached to left of button
  • center : menu centered on top of button


To use a FlyoutMenuView, you must provide a FlyoutMenuView.Adapter (which provides FlyoutMenuView.MenuItem instances) and a FlyoutMenuView.Layout which describes how to position the items in the menu.

You must also provide a subclass of FlyoutMenuView.MenuItem to render your items. You may also subclass FlyoutMenuView.ButtonRenderer to render your trigger button, if you don't want to assign a Drawable.

Here's an example implementation of FlyoutMenuView.MenuItem and FlyoutmenuView.ButtonRenderer which draws a simple unicode character. I use it in the demo app to render emoji.

public class EmojiFlyoutMenu {

	static String getEmojiByUnicode(int unicode){
		return new String(Character.toChars(unicode));

	public static class MenuItem extends FlyoutMenuView.MenuItem {

		int emojiCode;
		String emojiString;
		TextPaint textPaint;

		public MenuItem(int id, int emojiCode, float size, @ColorInt int color) {
			this.emojiCode = emojiCode;
			this.emojiString = getEmojiByUnicode(emojiCode);

			textPaint = new TextPaint();

		public int getEmojiCode() {
			return emojiCode;

		public void onDraw(Canvas canvas, RectF bounds, float degreeSelected) {
			canvas.drawText(emojiString, bounds.centerX(), bounds.centerY() - ((textPaint.descent() + textPaint.ascent()) / 2), textPaint);

	public static class ButtonRenderer extends FlyoutMenuView.ButtonRenderer {

		int emojiCode;
		String emojiString;
		Paint paint;
		TextPaint textPaint;

		public ButtonRenderer(int emojiCode, float size, @ColorInt int color) {


			paint = new Paint();

			textPaint = new TextPaint();

		public int getEmojiCode() {
			return emojiCode;

		public void setEmojiCode(int emojiCode) {
			this.emojiCode = emojiCode;
			this.emojiString = getEmojiByUnicode(this.emojiCode);

		public void onDrawButtonContent(Canvas canvas, RectF buttonBounds, @ColorInt int buttonColor, float alpha) {
			textPaint.setAlpha((int) (alpha * 255f));
			canvas.drawText(emojiString, buttonBounds.centerX(), buttonBounds.centerY() - ((textPaint.descent() + textPaint.ascent()) / 2), textPaint);

To use the above:

FlyoutMenuView smileyFlyoutMenu = findViewById(; 

int[] emojiCodes = {
		0x1F60D, //smiling face heart shaped eyes
		0x1F605, // smiling face with open mouth and cold sweat
		0x1F60A, // smiling face
		0x1F613, // face with cold sweat
		0x1F61E, // disappointed face
		0x1F620, // angry face
		0x1F62D, // loudly crying face
		0x1F4A9, // pile of poo

@ColorInt int color = ContextCompat.getColor(this, R.color.smileyMenuCharColor);
float fontSizeInMenu = getResources().getDimension(R.dimen.smiley_menu_item_size) * 0.5f;
float fontSizeInButton = getResources().getDimension(R.dimen.flyout_menu_button_size) * 0.5f;

// build a List<> of EmojiFlyoutMenu.MenuItem
List<EmojiFlyoutMenu.MenuItem> menuItems = new ArrayList<>();
for (int code : emojiCodes) {
	menuItems.add(new EmojiFlyoutMenu.MenuItem(menuItems.size(), code, fontSizeInMenu, color));

// assign a GridLayout with 2 columns and unspecified rows (allows menu to grow vertically)
smileyFlyoutMenu.setLayout(new FlyoutMenuView.GridLayout(2, FlyoutMenuView.GridLayout.UNSPECIFIED));

// assign the menuItems via an ArrayAdapter
smileyFlyoutMenu.setAdapter(new FlyoutMenuView.ArrayAdapter<>(menuItems));

// create and assign the button renderer. we'll change the button renderer's emoji in the callback below
final EmojiFlyoutMenu.ButtonRenderer renderer = new EmojiFlyoutMenu.ButtonRenderer(emojiCodes[0], fontSizeInButton, color);

smileyFlyoutMenu.setSelectionListener(new FlyoutMenuView.SelectionListener() {
	public void onItemSelected(FlyoutMenuView flyoutMenuView, FlyoutMenuView.MenuItem item) {
		// user has selected an item. update the button renderer's emoji to match
		renderer.setEmojiCode(((EmojiFlyoutMenu.MenuItem) item).getEmojiCode());

	public void onDismissWithoutSelection(FlyoutMenuView flyoutMenuView) {
